Detailed error in response when File too large for upload

[socraticDevBlog]

we are using aws Api gateway + lambda integration. there is a tight limit for upload content. a few MB; not more than 6

when uploading a larger paste (maybe a large file), im pretty sure api-gateway or lambda returns a “413 Request Entity Too Large” error

make sure this error gets returned by Pastebin API (http code 413, message "request entitiy too large"

desired change
